General description

3 units of 2 μmol product per set.

Application

Used for the preparation of nitrilotriacetic acid (NTA) -terminated self-assembled monolayers (SAMs) on gold surfaces as biosensors detected by SPR (Surface Plasmon Resonance)

Preparation Note

Suggested method for the preparation of NTA-SAM surface on a gold substrate.
1. Add 1ml of ethanol to a tube; and pipette to dissolve the reagent to prepare 2 mmol/L NTA-SAM solution. Dilute the solution 10-fold with ethanol for the next step.
2. Clean a gold surface of a substrate with Piranha solution prior to preparing NTA-SAM. Immerse the substrate in the prepared reagent solution and incubate overnight at room temperature.
3. Wash the substrate several times with ethanol and purified water sequentially.
